Title:
MILLIMETER-WAVE PHASE SHIFTER DRIVING APPARATUS FOR PREVENTING DISTORTION
Document Type and Number:
WIPO Patent Application WO/2023/085845
Kind Code:
A2
Abstract:
Disclosed is a millimeter-wave phase shifter driving apparatus for preventing distortion. The disclosed apparatus comprises: a motor; a moving member moving by means of the motor; a sliding member disposed a predetermined distance away from a reflective plate, and comprising at least one sliding bar coupled to the moving member so as to slide horizontally; and a guide member fixed to the reflective plate and for guiding the movement of the at least one sliding bar. The guide member comprises: a body part; a first supporter extending downward from a first lateral portion of the body part so as to come into contact with the reflective plate; a second supporter extending downward from a second lateral portion of the body part so as to come into contact with the reflective plate; and an insertion part protruding upward from the body part, and forming, in the protruding area, a square-shaped insertion hole in which the sliding member is to be inserted, wherein the height of the first supporter and the second supporter is determined on the basis of the distance between the reflective plate and the sliding bar. The disclosed apparatus prevents characteristic deterioration which may occur due to shaking and distortion in a millimeter-wave band, prevents components included in the phase shifter from falling off, and could be assembled easily.
